For one must recognise that the word ἀγένητον with only one
‘ν’ signifies
“uncreate” or “not having been made,” while
ἀγέννητον written
with double ‘ν’
means “unbegotten.” According to the first
significance essence differs from essence: for one essence is
uncreate, or ἀγένητον with one
‘ν,’ and another is
create or γενητή. But in the
second significance there is no difference between essence and
essence. For the first subsistence of all kinds of living
creatures is ἀγέννητος
but not ἀγένητος.
For they were created by the Creator, being brought into being by His
Word, but they were not begotten, for there was no pre-existing form
like themselves from which they might have been born.
